That we may then avoid this error, let us consider that death never comes by any defect of the soul, but only because some one of the principal parts of the body is corrupted; and conceive that the body of a living man differs as much from that of a dead one, as a watch or any other AUTOMA (that is any kind of machine that moves of itself) wound up, having in itself the corporeal principle of those motions for which it was instituted, with all things requisite for its action, and the same watch or other engine when it is broken and the principle of its motion ceases to act.
